This thread reminds me of that old Cheech and Chong segment from the 70s where Officer Friendly comes to school for the anti-drug lecture.

It was something like Officer Friendly shows the students a baggie of marijuana and asks "OK kids, does anybody know what this is?"

Student replies:

"That's Columbian Red!"

"No man! No! That's Oaxacan!"

"BS! That Michoacan!"
